WASTE-VALVE.

Specification of Letters Patent.

Patented Jann 29, 1918.

Application filed August 24, 1917. Serial No. 187,973.

To all whom it may concern.

Be it known that we, iViLLIAM FRANKEN- nn'nosn, residing at Louisville, in the county of Jciierson and State of Kentucky. and HALLOCK N. GILLETTE, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, both citizens of the United States, have invented or discovered certain new and useful Improvements in Waste Valves, of which improvements the following is a specification.

Our invention relates to waste valves used in connection with lavatories, bath tubs,

etc., and wherein a vertically movable stopper is raised to, and held in, open position by means of a rotatable or rocking member. its object is to provide a Waste valve which is simple and inexpensive in construction and in which the movement of the finger to taken on the line Ill-H, Fig. 1.

While our invention is applicable to varieus types of receptacles, it is shown herein in its adaptability to a lavatory bowl 1 of well known construction.

In the illustrative embodiment of our invention the waste opening at the bottom of the bowl is' provided 'with a vertically disposed valve casing 2, having a valve'seat 3 at its upper end. Vertically movable in such casing is a stopper having a head 4' adapted to rest upon the seat 3 to prevent flow from the bottom of the bowl through the valve casing. The lower end of the stopper is provided with a tapered, preferably a conical, face 5, the purpose of which will presently be explained.

For raisingthe stopper to, and holding it in, open position, a finger 6 is secured to the end of a shaft 7 rotatably mounted in the side of the casing 2. As indicated in the drawings, the shaft 7 is, for simplicity of construction, rotatable on an axis substantialiy perpendicular to that of the stopper and lying in a plane common with the stop;

per axis. Means are provided, preferably in the form of lugs 8 and 9 formed integrally with the interior of the casing 2, for limitmg the alternate movements of the finger,

When holding the stopper in raised position, the finger 6 is in the position indicated in Fig. 2, the outer end of the finger being provided with a tapered face, which, in the position indicated, substantially registers with the conical lower end of the stopper. It will thus be seen that the line of thrust of the stopper upon the finger is at the side of the axis, of rotation of the shaft 7, so that the stopper may not, by pressure thereon,- be moved downwardly as long as the finger is insuch position. To effect a lowering of the finger to permit the stopper to fall to closed position, the stopper is preliminarily raised, and in addition to this resistance to the lowering of the finger, there is a further resistance to such movement arising from the extended frictional contact of the tapered face of the finger with the conical face of the stopper. As is usual in valves of the type contemplated herein, a vertically movable rod 9 is gar 6. Preferably the outer end of the shaft is of angular cross-section for the attachmerit of an arm 10, which, through a link 11, is connected to the rod 9. By attaching the arm 10 to one side or the other of the shaft 7, the rod 9 may be' either raised or lowered to efiect the lifting of the stopper. As shown herein, the arm is soattached that the pulling or raising of the rod efi'ects an opening of the valve, that is to say, 0. raising of the stopper. By constructing the'finger and stopper, and arranging them in the manner described, the weight of the vertically disposed rod 9 and link 11 will not in itself be effective to turn the shaft 7 tolowerthe finger 6, and thus unintentionally close the waste valve.

According to the provisions of the patent statute, we have described the principle and operation of our invention together with the construction which We now consider to represent the best embodiment thereof. However we desire to have it understood that our invention may be practised by other W e claim as our invenfien:

1? In a Waste valve, the combination of a casing, a stopper vertically movable therein and having a tapered face at its lower end, a lifting finger beneath The stepper mtaiable upon. an axis substantially perpendicular t0 and lying substantially in the same plane as that of the stopper, and means fer liiniiing the alternate movelneni of iili? finger, (he line of thrust of the stopper upon the finger when the stopper is in elevated position be ing at one side 01 the axis of relation ef' gel to permit the stopper -0 fall will a preliminary raising of iilie stepper.
